A shrapnel ball mill

Abstract

The invention relates to an elastic piece ball mill which mainly comprises a rack, a driving motor, a bearing, a tank body, a casing and a grinding medium, wherein the tank body is wrapped with the casing arranged on the rack; the casing is connected to the bearing through a shaft, and can rotate along the bearing; elastic mechanisms are arranged on the inner peripheral wall of the tank body; each elastic mechanism comprises an elastic piece and a lifting rod; strong magnetic pieces are arranged at the bottoms of the lifting rods; strong magnets opposite to the strong magnetic pieces one to one are arranged on the lower half cylindrical surface of the inner wall of the casing; the magnetism of each strong magnet forms homopolar repulsion or heteropolar attraction with that of the strong magnetic piece opposite to the strong magnet. According to the ball mill, the grinding medium can be actively ejected to increase impact force after reaching a certain height, and in addition, materials can be completely dispersed to be ground more completely; the materials can be ground at higher speed.

Description

technical field [0001] The invention relates to an industrial crushing equipment, in particular, a ball mill. Background technique [0002] In industrial aluminum smelting, it is necessary to grind the broken aluminum ore to facilitate subsequent processing operations; at present, the commonly used grinding device in industry is a ball mill; when using a ball mill, the speed of the tank in the ball mill needs to be adjusted to a certain speed. Ensure that the internal grinding medium is in a throwing state; this kind of throwing state means that the grinding medium moves up with the inner wall of the tank to a certain height and then falls in a parabolic trajectory, and finally hits the material, thereby realizing the grinding and crushing of the material; the traditional ball mill relies on the tank The friction of the internal wall drives the grinding medium to move upwards and make it fall freely.

[0002] In industrial aluminum smelting, it is necessary to grind the broken aluminum ore to facilitate subsequent processing operations; at present, the commonly used grinding device in industry is a ball mill; when using a ball mill, the speed of the tank in the ball mill needs to be adjusted to a certain speed. Ensure that the internal grinding medium is in a throwing state; this kind of throwing state means that the grinding medium moves up with the inner wall of the tank to a certain height and then falls in a parabolic trajectory, and finally hits the material, thereby realizing the grinding and crushing of the material; the traditional ball mill relies on the tank The friction of the internal wall drives the grinding medium to move upwards and make it fall freely. The gravity of the grinding medium itself is limited, so the impact force at the bottom of the falling is limited, and the grinding level of the material is limited; in addition, due to the high speed, the grinding medium will It rotates synchronously with the inner wall of the tank, making it unable to work normally, which greatly limits the working efficiency of the ball mill
